I have a relative who works for the NHS and endlessly takes advantage of all these NHS discounts, offers, etc - she gets money off on supermarket shopping for goodness sake. Meanwhile, she earns more than I do (which I don't begrudge, she does an important job). I'm not sure why companies give these offers (that the rest of us are funding) to often well-paid NHS professionals.
I work in education and have a TOTUM card (which I use with EE among other things) but the available discounts pale in comparison to the largesse showered on our NHS friends.
